I am reminded of the old saying---you don't have to know what's under the hood in order to drive the car. I am still struggling with trying to explain the RSS concept to others, but I can at least drive the car.
I subscribed to krl2pt0, the Darien Library Books, and two KRL blogs which interest me for different reasons. "A Street Where Cats Gather" is confident and cruising. Something to inspire me. "Dragging My Feet" is the account of someone who is struggling. I can identify and have empathy for dragging.
Finally, I was in the mode and couldn't help myself so just for the heck of it I also subscribed to Media Matters and Buzz Flash. Might as well hit all of my guilty pleasures in the same day.
